PURPOSE:To generate a sampling digital data being corrected to a sampling time position of a prescribed sampling period by using a digital data of an input sampling signal so as to apply interpolation arithmetic thereby obtaining a digital data at the sampling position of an output sampling signal after the correction. CONSTITUTION:Digital data CD01, CD02, CD03- whose phase is deviated by a phase quantity corresponding respectively to the quantities of correction DELTAtheta1, DELTAtheta2, DELTAtheta3... of a phase error signal SVE from the sampling timewise positions t01, t02, t03... based on digital data VD01, VD02, VD03... of the input sampling signal VDIN are subject to interpolation operation in a sampling signal phase correction circuit 21. Then the digital data subject to interpolation in the timing of the sampling timewise positions t01, t02, t03... is sent as the sampling digital data CD01, CD02, CD03... of the output sampling signal DVES after the correction. |
